And you thought windows were for looking THROUGH:

Windows that double as television screens, computer monitors or stereo systems are being unveiled today, on the first day of the International Builders' Show in Las Vegas, by Andersen Corp., the country's largest window manufacturer.

The new windows are the latest advance in a growing industry, fueled by record new-home sales, bigger and bigger houses, and a burgeoning remodeling industry. In 2002, 56 million windows were produced in the country, up from 47.9 million in 1996, according to the Window and Door Manufacturers Association. New windows are purchased in about equal numbers for new homes and remodeling projects, according to the association.

Minnesota-based Andersen's new entrant, which isn't for sale yet, is a bay window that doubles as a home entertainment center. A low-voltage electric current runs through the window. When the current is on, the window is clear. But flip a switch to turn the current off and the glass goes opaque, allowing it to be used as a projection screen for watching television or DVDs. The flanking casement windows become the speakers.

The company is also showing a window featuring an embedded touch-screen computer that slides into a pocket in the window frame when not in use. Andersen and other large window manufacturers are also introducing several other designs in windows and screens at the annual trade show, which runs through this week.
